Has anybody had experience with the chirping rattling serpentine belt? I've since found out from various people that the most likely culprit is the alternator clutch seized up. The tensioner is dancing around like crazy on idle. Any revs above 1000 it sounds normal and the tensioner does not move about. My plan is to keep the revs up when in traffic etc. Normally I wouldn't drive when something snot right however tomorrow I'm going to Belgium at 4am for the day. I'm hoping its going to hold....how long have people left theres??
